Lenovo 16GB DDR4 SoDIMM

This Lenovo-branded module delivers 16GB of DDR4 memory in a 260-pin SoDIMM form factor. It operates at 2666MHz with a PC4-21300 rating and runs at 1.2V. The stick is unbuffered and non-ECC, making it suited for standard desktop or workstation upgrades where a single 16GB module is required.

DDR4 2666MHz practical limits

DDR4-2666 sets the maximum transfer rate at 2666 MT/s, so the module cannot exceed this speed regardless of motherboard capability. The PC4-21300 designation reflects the peak bandwidth ceiling for this standard. Systems limited to lower DDR4 speeds will downclock the module automatically, while platforms without DDR4 slots cannot use it at all.

Intel XMP 2.0 profile support

The only performance feature listed is an Intel XMP 2.0 profile, which allows the memory to run at its rated 2666MHz when enabled in a compatible BIOS. Without XMP support the module will fall back to the default JEDEC speed for the platform. Buyers who need manual timing control or higher validated speeds should look elsewhere.

Questions about this item

Is the 16GB capacity the only option for this Lenovo 4X70W30751TM module?

This specific part number identifies a single 16GB DDR4 SoDIMM; other capacities would carry different part numbers

What does the 2666 MHz rating mean once the stick is installed in a desktop?

The memory will operate at up to 2666 MHz DDR4-2666/PC4-21333 when the platform supports that speed, otherwise it will run at the highest common speed the system allows

The spec lists a 260-pin SoDIMM form factor — what interface does that use and what does it limit?

The 260-pin SoDIMM connects via the standard DDR4 laptop-style slot, which electrically caps the module to DDR4 signalling and the rated 2666 MHz data rate
